I picked up my lower today and ordered my lpk last night (Daniel Defense...I knew I would be picking up lower today). Well, I got to thinking that I really want to assemble every part on my rifle, so I started looking at Uppers an Stocks and what not. The reason I want to assemble every piece myself, is because I really want to know all the inner workings of my rifle. Mainly because, in case something breaks, then I will know how to disassemble it and repair it.

My dilemma comes in, is this a smart thing to do to completely assemble it myself or should I just buy a completed upper with barrel?
